Single Inductive Loop Presence Detector Relay Output Vehicle Access Control System

Relay Output vehicle access control system Single vehicle inductive loop presence detector

About loop detectors

Loop detectors are used wherever vehicles have to be detected, for example: monitoring and safe guarding access ways or counting vehicles. The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.
SINOMATIC loop detector with direction detecting function that can be used to statistics the vehicle flux. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.

Technical Data
Power Consumption: 4.5VA
Output relays: 240V/5A
Operating temperature: -20°C to +65°C
Storage temperature: -40°C to +85°C
Signal holding time: Unlimited / limited when loop is permanently covered 10 minutes
Sensitivity: Adjustable in 4 increments
Loop inductance: Total loop plus connection wiring: 50μH to 1000μH(Ideal is 100μH to 300μH)
Loop connection wiring: Maximum length 20 meters, twisted at least 20 times per meter

Main Features:

1) Reset Switch : The reset switch enables the detector to be manually reset during commissioning and testing . This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection ;

2) Selectable Pulse Time : This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds ;

3) Pulse Relay Selection : The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop ;

4) Sensitivity Boost : This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles ;

5) Switch Selectable Sensibility : 4 sensitivity setting are available on the switches to allow flexibility in configuration ;

6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;

7) Filter Option : This option is used to provide a delay between detection of the vehicle and switchiing of the output relay . This relay is normally used to prevent false detection of small or fast moving objects ;

8) Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods .
